r Values

< Back
Total R value is the total of each and every element that makes up the
construction of a building, and includes wall/ceiling/underfloor
applications such as brick, plaster, internal air, cement sheeting and
so on.

Added R value is what the Foilboard® Insulation Panel combined with the
adjacent still reflective airspaces adds to a particular system. The
actual amount of airspace adjacent to the material will have a profound
impact on the R value – the larger the space, the higher the R value.
If the airspaces are ventilated or classified as open the R values will
not be very high at all.
